On iPhone UITextField auto-scroll « The Loop. During my early days of iPhone development, I came across this specific problem: How the heck do I auto-scroll the text fields behind the keyboard?

Hidden text fields The iPhone's onscreen keyboard occupies the bottom 216 pixels on screen (162 in landscape mode).
That's around half the screen, so if you ever have a text field you want to edit in the bottom half of the screen, it needs to move or it will get covered. You can just animate the whole window upwards by the height of the keyboard when editing a text field in the bottom half but this doesn't work well for text fields in the middle (they can get moved too far up).
